Jakcom R3 NFC Smart Ring Electronics Mobile Phone Accessories compatible with Android IOS SmartRing Smart Watch (9#)

The ring barely works. Half the time, you hear the sound that it works, but, it's not doing anything. There is no app on the google play store. When you finally find the app online, it does nothing but open other apps. It does not count your steps or anything else. It is very basic. I will not recommend it to anyone. Oh, it comes with NO instructions on how to setup or use it at all. I will be returning mine.

They don't advertise this thing as anything other than an nfc ring and it's great at that. Unlike what I thought you don't have to choose nfc m1 or I'd protocols, one ring has them all. This thing STORES information in the nfc tags on it. My phone can read the m1 side and the nfc side. And writes to them both not to the id side but as I've researched that's normal. Read up on what an nfc tag can do, this is basically 2 or 3 of those strapped to your finger

The ring comes with no instructions for the user. Once you download the app gives you the instructions in chinese or some other asian language. It does not work with apple devices.For some reason the app ask you for permission to access your pictures and geographic location.The business card part, notes, and phone quick app launch is really cool, but only works on Android devices.

Tarnished after 1 day of wear. NFC seems to work. Haven't been able to test the other rfid chips yet. My proxmark rdv4 seems to read them but is really particular about orientation.

Okay product. Work with some smart phone.

Didn't wwork or conect with my android galaxy Note 3

not bad but they some thing am trying to figure out what the app

False Advertising! The ID and IC functions do not work! This ring does nothing.
